Got me there. [Kaiba huffed, drawing himself up to his full height. Despite the time spent here he was still seeking clarity on that himself.] There are multiple theories being bandied about, but without solid evidence to lead to a conclusion. Believe me, if I knew- I wouldn't still be here. [For someone like him that was used to troubleshooting on the fly, not being able to pin it down was almost a personal affront]

I'm still of the opinion that this is a simulation, it would account for the inconsistencies in the environment. [He wasn't really in the mindset for a Q&A but he better expand on that before the guy could ask] Initially, there wasn't anything here... like .. this. [Motioning to the whiteness all around them] .. but since then a mountain sprung up, forest and various structures. The appear at random, and are always altering.

It can't be real. [Just putting that out there now. He did not share the opinion that anyone was meant to meet. The stranger had the wrong duelist for that.] So what are you supposed to be?
